Read and follow all installation instructions

WARNING

 

FuelCAN is a compact interface for translating an analogue  
fuel level sender signal into digital SAE J1939 CANbus data. 
The device allows integration of standard fuel level senders 
into modern ECU-based engine instrument and control 
systems. 
FuelCAN modules have three inputs (only one of which is 
connected at any one time): input 1 is configured for use with 
Murphy ES series resistive fuel level senders; inputs 2 and 3 
can be used with fuel level senders having compatible 
resistance ranges.

Input 2

FuelCAN inputs can also be factory-configured for use with 
non-standard fuel level or resistive senders. Please note  
that minimum order quantities apply for custom solutions. 
A rear facing LED indicates input and CANbus status. 
FuelCAN is compact and light enough to be incorporated  
into wiring harnesses, but can also be surface mounted via 
four case holes. The polycarbonate case is fully sealed in 
epoxy resin for high impact and environmental resistance. 

These instructions relate to Murphy part number 79.70.0006. 
FuelCAN modules with other stock codes may include 
modified input scaling or CANbus/J1939 data parameters.
